I've been WFP for 4 weeks now (or is it 5?).
I started tops only, with my mate catching up down trad.
This last 2 weeks, i've been doing up's and down, with my made doing the odd difficult access or odd house where we cant WFP.
I cant believe the time we have saved. We have a backpack also, so now we will be doing WFP up and down wherever possible.
Now this may mean a trip home to re-fill, but we are earning 20+% more, even though we are still on first cleans.
I don't think I will be going back to up only any time soon
